Physiognomy: Ad B-Forb

A native of Eurasia, sometimes a locally common weed of roadsides, dumps, railroads, forests, thickets, and gardens. First collected in 1890 in Kent Co.

The foliage is very similar to that of Stylophorum, but the cauline leaves are clearly alternate and the petals are distinctly smaller (ca. 8–14 mm long). A double-flowered form is sometimes cultivated and also escapes. The bitter sap of this plant, as of many other members of the family, has long been thought to be of medicinal value although fundamentally poisonous.
